This invention relate t0. a carbureting p osive engines', ond is `moreespecially 1.11- lThe principal object 'is to provide a devioe`ofthischaracter that will automaticallycontrol and regulate the admission andnuxin of the ,explosive charge. l l .n carrying out thc objects of' thisinwontion, means arc'cm .loyed which will simul-y taneously, control tproportions to lsecure the greatest` eilicieney. A practical embodimentof the invention islillustmted in the accompanying drawings.

into manipulated by disk l2. The valve C bein in its lowest position,the collar 20 is adjusted to leave a space 21 between it and theunderside of the end disk 12. The spaces 19 and 21 a1eprc cau 6 tionaryas against back explosions and when one occurs the pressure is relievedthrough these passages and injurious effects avoided. lVhen the engineis in motion some air will always pass up through the spaces 19 and 21the mixing chamber, but this is provided as a part of the supply only.lVhen the valve is raised, the space between the end disk l2 andthecollar-5.20 is'increased. Thisjcollar is set by the maker; of the car-15 bureter to determine the initial flow of air through passage 19. Theinflow of air at -thispoint is, of course, limited by the size ofpassage 19, while the flow through ports- 15 has a wider range ofvariation. v

valve rod 22 extends1 up through the A tubular post 18 and has a needlevalve 23 formed on the upper end thereof. The lower en'd of rod 22passes through and is threaded in a part of a 'stuiiing box 24. and ismeans of the handle end 25 in adjusting the position of the needlevalve. The gaseous element.`enters the apparatus through a tubular`connection 26 and passes up through the space 27 between 30. the valverod 22 and the surrounding wall of the tubular post 18 into the; mixingchamber 16.

A bridge 28 is mounted on the end disk 3-5-12 of valve C and arches overthe upperend of the tubular,.post and the needle valve. "The'upper endofthe post presents a conical surface 2 9 and the bridge is provided inthe underside with a corresponding seating 1` cavity 30, forming adownwardly deflecting stopper which, whenthe valve C is 1n itsclosedposition, engages the upper end of the tubular post and closes thepassage past the needle valve and when the valve is raised directs thehydrocarbon. downwardly and laterally into the currents of air. Thus thevalve C is supported from the upper end. of the tubular post in asuspended posltlon when the engine is at rest. VBy this arrangementcombination valve'C with its central gas port and its central andcircumferential air ports automatically controls and pro- 'portions theadmission ofboth the airand gaseous elements into chamber 16 1naccordance with the working demand 'of the engine. The valve C willordinarily avitate into its closing'position, ,but is asslsted by-comTjaanion'springs 31 coiled on compamonrods 32 inserted inthe lower endsvof two ofthe valve ribs and located at opposite sides. The nuts 33provide means'for adjusting the tension of said springs. When thegaseous element flows into the mixing ychamber 1t.1m

r pingesagainst the underside of the. bridge and is forced out laterallyindifferent direc- 35 tions.v The air as it enters into the mixingchamber 16 through the center port 19 and the` circumferential ports 15,entirely surrounds' thein'comin gaselement so that a thorough mixture oing the explosive charge is effected. The' inner circumferential surfaceof that portion of the casing inclosing the mixing chamber is providedwith a number of inclined vanes 3l and acts to impart a spiral whirlingmotion to the elements forming the explosive charge and assist in the oeration of mixing. The shoulders 35 formed on the vanes 34 limit the upor open movement of the valve In practical Working. the valve has a verysensitive vibratory action and instantlyl responds to the slightestvariation of speed in the engine and admits mre or less of the gaseousand air elements as required.

A throttle valve 36 is mounted on -a stem 37T and locatedin the passage38 .in the casing part A which connects with the tubevor pipe.conducting the explosive charge into the engine cylinder. A crank arm ismounted on the outer extended end of stem 37 and 'provides 'for theoperative connection with the mechanism under control of the operator. 4
